Cystoid macular oedema following retinal detachment surgery

There are limited studies examining the incidence and risk factors for postoperative cystoid macular oedema (CMO) following rhegmatogenous retinal detachment (RRD) repair. Postoperative CMO is thought to be due to pro-inflammatory state, where numerous cytokines lead to tight junction dysfunction,...

The effect of everolimus on retinal pigment epithelium and proliferative vitreo-retinopathy

The principal cells involved in proliferative vitreo-retinopathy (PVR) are retinal pigment epithelial cells (RPE). Everolimus is a drug used in renal cell carcinoma which targets and inhibits a key regulatory protein in cancer (mTOR). In this study, the authors investigated...

Intraocular surgical training – is there any inter-procedural transfer of skills?

Cataract surgery is the most commonly performed surgery during ophthalmology training. This study aims to investigate how experience in simulated cataract surgery impacts and transfers to the learning curves for novices in vitreoretinal surgery. Twelve ophthalmology residents without previous experience...

Radiation retinopathy

The authors review the current treatment options for this condition. Radiation retinopathy (RR) occurs as a complication after exposure to any type of radiation (external beam, plaque brachytherapy and stereotactic radiosurgery) in the orbital or adnexal region. These include nasopharyngeal...

What’s next in retinal imaging? Faster, deeper and full-on

Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...

Ocular Dirofilariasis: a diagnosis on the rise?

Dirofilaria repens is one of 40 species of Dirofilaria. It is a zoonotic filarial nematode that commonly impacts dogs, however, human infection can occur through affected organs like skin, lung and eyes [1]. Although, there have been case reports of...

Ocular electrophysiology

A 34-year-old woman, who is a CEO in a multinational firm, has been losing vision over the last 12 months. She has seen her opticians, who initially tried different glasses but could not improve things. Clinical examination is unremarkable. How...

Existential Crises

Over the past few years and months, I have noticed increased numbers of my colleagues from all over the UK complaining about various problems with their jobs and life in general, and it seems that since the COVID-19 pandemic the...

Phaco nightmares

I am interested in the stressful nature of cataract surgery from the surgeon rather than the patient’s perspective. It is an issue that has quite literally kept me awake at night. Part of getting to grips with a problem is...

The assessment of pupils and 
pupillary reactions

Understanding pupillary reactions is vital in understanding basic neuro-opthalmology. It is a skill required in eye casualty, clinics and perhaps most importantly, exams. To start at the beginning, the pupil is the central aperture of the iris, its size controlling...

A paradigm shift in the way we approach cataract surgery

Cataract surgery is the most common elective surgical procedure in the UK [1], with in the region of 350,000 cases being conducted each year. With an ageing population, this figure will only continue to rise over time. Cataract surgery is...

Pathological myopia: a trainer’s perceptive

High myopia is defined as myopic refraction of greater than -6 dioptres with an axial length greater than 26.5mm, while pathological myopia is myopic refraction with posterior pole degeneration [1]. These degenerative changes can affect a young population and in...
